Comparison of the advantages of ammonia gas stripping to produce urea and carbon dioxide gas stripping to produce urea!

recommend: 1. "Fertilizer Industry" Issue 01, 1998 New progress, comparison and evaluation of ammonia stripping and carbon dioxide stripping urea production technologies [Abstract]: Through the inspection of urea patentees and production equipment of ammonia stripping method and carbon dioxide stripping method, we learned about the progress of these two technologies in recent years, compared the production operations, equipment materials, investment and other aspects of these two technologies, and evaluated them based on the actual domestic production. author: Tang Wenqian Shandong Chemical Planning and Design Institute

Opinions on gas stripping urea production technology - personal opinion of Guo Zhenying, China Tianchen Chemical Engineering Company, and "ammonia stripping and carbon dioxide stripping urea production technologies": Advantages of full circulation of aqueous solution - it is more convenient to increase or decrease the production load, and the operating elasticity range is wide ； The potential for increasing production is relatively large. The corrosion of the aqueous solution full cycle urea device is relatively light, especially the corrosion rate of the urea tower and medium-pressure decomposition and heating equipment. During normal production, the oxygen content in the CO2 gas can be controlled at 0.5%~0.6% to meet the requirements. ； Furthermore, the high-pressure system equipment of the aqueous solution full-circulation urea process is relatively small, and the medium and low-pressure system equipment is more convenient to stop for maintenance. Therefore, whether it is system overhaul or ordinary small and medium-sized maintenance, it is more convenient and the maintenance time is relatively short.
